There's a lot going on in the world of Mac apps for popular AI services. In the past week, Anthropic has released a desktop app for its popular Claude chatbot, and Perplexity launched a native app for its AI-driven search service.

On top of that, OpenAI updated its ChatGPT Mac app with support for its flashy advanced voice feature.

Like the ChatGPT app that debuted several weeks ago, the Perplexity app adds a keyboard shortcut that allows you to enter a query from anywhere on your desktop. You can use the app to ask follow-up questions and carry on a conversation about what it finds.

It's free to download and use, but Perplexity offers subscriptions for major users.

Perplexity's search emphasis meant it wasn't previously a direct competitor to OpenAI's ChatGPT, but OpenAI recently launched SearchGPT, a search-focused variant of its popular product. SearchGPT is not yet supported in the desktop app, though.

Anthropic's Claude, on the other hand, is a more direct competitor to ChatGPT. It works similarly to ChatGPT but has different strengths, particularly in software development. The Claude app is free to download, but it's in beta, and like Perplexity and OpenAI, Anthropic charges for more advanced users.

When ChatGPT launched its Mac app, it didn't release a Windows app right away, saying that it was focused on where its users were at the time. A Windows app recently arrived, and Anthropic took a different approach, simultaneously introducing Windows and Mac apps.

Previously, all these tools offered mobile apps and web apps, but not necessarily native desktop apps.
